Methods: clinical, mathematical modeling, experimental, statistical. It is proved that the mechanism of pressing the joint surfaces in the shoulder joint due to the difference intra and atmospheric pressure, is the primary factor in stabilizing the shoulder joint, and increases the effect of stabilizing the head of the humerus with muscular exertion. The effectiveness of this mechanism remains provided the area articular surface of the blade is twice the area of ??the defect articular surface of the humerus head. Mathematically it is proved that the defect of the head of the humerus is more than ? the articular surface of the blade and has an angle less than 60 ° inklinatsiyi is critical to the stability of the shoulder joint. Shown experimentally that the greatest strength of anchor fixation provides IPHS beyond for this indicator Stryker anchor almost doubled and nearly five times the quality perosseous fixing seam. The triangular 2-mm anchor that samozaklynyuyetsya less than 30% yields for this indicator Anchors Stryker, but almost one and a half times the quality perosseous fixing seam. The algorithm scheme and choice of tactics of surgical treatment of shoulder joint instability injuries combined with Bankart and Hill-Sach, based on the size of the defect head and shoulder inklinatsiyi his corner. The algorithm scheme and choice of tactics of surgical treatment of shoulder joint instability injuries combined with Bankart and Hill-Sach verified and have been clinically tested. Stability and instability of the shoulder joint, mechanisms to stabilize the conceptual and mathematical modeling Product Description popup.authors Біцадзе Марьяна Зауріївна Васильцова Людмила Анатоліївна Гузь Евгенія Валеріївна Демченко Дмитро Олександрович Демченко Олександр Васильович Зінченко Вікторія Вікторовна Карпінська Олена Дмитрівна Карпінський Михайло Юрійович Кондрашова Олена Іванівна Маколінець Василій Іванович Паздніков Роман Володимирович Суббота Ігор Анатолійович Тяжелов Олексій Алімович Яресько Олександр Васильович popup.nrat_date 2020-04-02 Close
